/* vstudio.css - the Virtual Studio (includes/music/vstudio.php, assets/music/sas/vstudio.js). The room is the hero: on a
   wide screen it takes two thirds with the controls in a panel on the right; on a phone it fills the studio and the
   controls are a sheet that peeks at about 30% and drags up. House style: flat buttons (selected = a fill, pressed = a
   darker fill or scale(.98)), no one-sided borders, every handle 44 px or more, labels in chips off the lines, light and
   dark from the site's tokens. */
